The follo. description is directed to the specific forni and embodiment of the invention illustrated in the drawings and is not intended to limit the scope of the invention itself which may be practiced in a wide variety of forms and arrangements.

Adverting herewith to the specilic form of the invention illustrated in the drawings, a continuous running yarn Y passes between draw rolls l?. and l2. and enters a serpentine tube system ilrst through tube 13 and jet nozzle id, into tube l5, around bend lo, through jet nozzle 17, into tube 18, around bend i9, through jet nozzle 28, into tube 2l, thence around bend 22 and subsequently through jet nozzle Z3, into a fourth longitudinal tube 24, thence around bend 25 and through jet nozzle 26, into a fifth longitudinal tube 27 from which it passes out of the apparatus between delivery rolls 28 and 29.

To drive the rolls l2 and 29, an electric motor 39 is provided at the base of the apparatus having a shaft 3l to which are mounted pulleys 32 and 33 around which respectively pass endless belts 34 and 35 connected to pulleys 35 and 37 respectively keyed to shafts 3S and 39 of rolls l2 and 29, respectively.

The aforementioned serpentine tube system is housed in a steam cabinet having top and bottom walls i2 and 43, side walls 44 and 45, and front and rear walls 46 and 47. To the side wall d4 of the cabinet there is mounted a bracket 48 for the support of draw rolls ll and l2 and to the side wall 45 of the cabinet there is mounted a bracket 49 for the support of delivery rolls 28 and 29. Surrounding the tube 27 adjacent the exterior surface of 3\,ll idg Patented Nov. l2, 1963 "ice the wall l5 is a packing gland 5l). A steam inlet tube 52 leads into the cabinet through the base wall d3 and a condensate discharge tube 53 leads from the cabinet through the aforesaid base wall 43. The steam cabinet is supported above the electric motor Sti by legs 55.

Vents 55, 57, 53, 59 and 6@ lead, respectively, from the yarn carrying tubes l5, 1S, 2l, 24 and 27 and extend vertically to pass through the roof or top wall 42 of the cabinet. Fluid inlets 62, 63, 64, 65 and 66 lead to jets 14, i7, 2i), 23 and 25, respectively, for the admission of tluid into the aforesaid jet nozzles. Additional huid inlets 7@ and 7l lead through side wall l5 of the cabinet into bends 16 and 22 of the serpentine system and additional uid inlets 72 and 73 lead through side wall 44 of the cabinet into bends i9 and 25 of the serpentine system. FlGS. 3 and 4 illustrate the jet nozzle as provided in accordance with this invention and used in the practice thereof. let nozzle i4 is illustrated in FIG. 3 and jet nozzle 7 in FlG. 4, which jet nozzles are similar but operate in opposite directions in the serpentine system. Each jet nozzle comprises an elongated tube 75, which, in the case of jet nozzle lll, is adapted to enter into tube l5 concentrically so that a small annular space 76 separates the jet nozzle tube from the Wall of the tube l5. At the opposite end of the jet nozzle tube '75 there is provided a fitting 77 having a section of wider outside diameter 78 adapted to t onto the end of tube 13, in the case of jet nozzle l, and to the end of tube i6 in the case of jet nozzle 17. A section of lesser outside diameter 79 is adapted to hold the end of the jet nozzle tube 75. A litting Si is shaped to provide an enclosed annular space 32 outside the jet nozzle tube 75 and includes an inner concentric tube 3 extending therefrom along the outside wall of the tube 75 providing an additional annular space S4 between the aforesaid tube 83 and the outside wall of the tube 75. Another fitting S5 seals the tube section 83 to the tube 15, in the case of the jet nozzle lll-l, and to the tube lil in the case of the jet nozzle i7. Fitting 8l is provided with an opening in the side thereof having a Wall S7 into which extends inlet pipe 62 in the case of jet nozzle l and inlet pipe d3 in the case of jet nozzle 17.

In the practice of this invention, steam is introduced through inlet 52 under pressure into the steam-tight cabinet containing the serpentine system in order to obtain the temperature at which the yarn Y is to be treated. The ieat from the steam within the cabinet is transferred to the inside of the tube system where the yarn will pass. Where the yarn Y is to be heat-set, for example, air is admitted through the inlets 62, 63, 6d, 65 and 66 into the jet nozzles ld, i7, 2li, 23 and 26, which jet nozzles direct the air, respectively, into the tubes l5, l, 2l, 2d and 27. When, for example, the air or other iluid enters through the inlets 62 into the jet nozzle ld, air is received in the annular space 82 and passes through the annular space 54 and subsequently through the annular space 76 into the ube l5. Since the air passing through the inlets 62, 63, oli, 65 and 66 is conveyed a distance within the steamtight cabinet before reaching the respective jet nozzles 14, i7, 2t?, Z3 and Z6, the air contained therein is preheated prior to entering the serpentine tube system. The action or" the jet nozzles 14, i7, 2d, 23 and 25 in directing air into the respective tubes l5, l5, 2li 2d and 27 creates an area of reduced pressure at the delivery ends of tube 13 and bends 16, "i9, 22 and 25, as a consequence of which the yarn Y is drawn from the draw rolls l1 and l2 into tube 13, and the air passing through tube l5 carries the yarn to the bend i6. The action of the jet nozzle t7 then carries the yarn around the bend i6 and delivers the yarn into the tube l@ where the air carries the yarn Y again to the bend 19. The action aforedcscribed is continued in subsequent jet nozzles and tubes until the yarn is discharged from the tubular system to the delivery rolls 28 and 29. Where additional air is required to assist in carrying the yarn, or in someV cases, a fabric, around the bends 16, 19, 22 and 2.5, additional air is supplied to the aforesaid vents through supplementary inlets 7l?, 71, 72 and 73.

It will be clear that the rolls 1'1 and 12 and 28' and 29 are driven by the motor 30 and that the aforesaid rolls may be adjusted -to avoid any tension upon the yarn Y. The yarn Y, accordingly, may pass through the serpentine system in the steam-tight cabinet in a completely relaxed condition without any tension being exerted thereon by reason of the fact that the yarn is carried through the apparatus by jet streams of air or the like.

It will be further apparent that Where the yarn Y is to be dyed, a liquid dye may .be introduced into the serpentine system through the inlets 62, 63, 64, 65 and 66 or where the yarn Y is to be dye-set, rnoist air or steam may be introduced into the serpentine system through the aforesaid inlets. In fact, any lluid, even including molten metal, can be introduced into the system in the manner aforedescribed. It will be clear, too, that not only may textile yarns be treated in the apparatus according to the invention, 'but textile fabrics as well.

It will be evident also that the speed of the rolls d1 and i2 and 2S and 29 can be adjusted so that the rolls 23 and 29 operate more slowly than the rolls 11 and 12, thereby allowing a combination for shrinking the yarn or fabric if desired. In certain cases where it is desired to stretch the yarn, the speed of the delivery rolls 2S and 29 may be increased accordingly.

It Will be apparent that it is an important advantage of the invention that textile yarns or fabrics may be processed in a limp or relaxed condition without exerting any tension whatever thereon by means of the tube system and air jets which carr] the yarn or fabric along in rthe llow thereof.

Another important advantage of the invention resides in the manner in which the entire system is maintained within a steam-tight cabinet by means of which yarns or fabrics may be lsubjected to high temperatures without subjecting them to correspondingly high pressures.

Although this invention has been described with reference to specic forms and embodiments thereof, it will be apparent to those skilled in the art Ilthat various changes other than those referred to above may be made in the form of the device, t-ha-t equivalent elements may be substituted yfor those illustrated in the drawings, that parts may be reversed, and that certain features of the invention may be used to advantage independently of the use of other features, all within the spirit of the invention as defined in the appended claims.
